Problems solved by technology
[0004] The wires between the wire layers of the existing flexible circuit board are juxtaposed flat wires, and the direct gap between the main wires on both sides and the middle wire is generally 0.6mm. It is easy to cause the direct contact short circuit between the two main wires and the middle wire and be scrapped; at the same time, the main wires and the middle wires on both sides are not insulated and separated. During the use of the flexible light strip, especially the high-voltage flexible light strip, poor heat dissipation leads to Thermal breakdown caused direct contact short circuit between two main conductors and intermediate conductors and scrapped

The invention discloses a flexible circuit board and an LED soft lamp belt provided with the flexible circuit board. The flexible circuit board comprises a lead layer, an insulating layer and a solder mask layer; the lead layer comprises a first main lead, a second main lead and a packaging lead located between the first main lead and the second main lead, the first main lead, the second main lead and the packaging lead are arranged side by side, and the packaging lead is provided with a fracture for packaging an element; the insulating layer is disposed on a surface of one side of the lead layer; the solder mask layer is disposed on a surface of the other side of the lead layer, and the solder mask layer is provided with a window corresponding to the fracture; and the flexible circuit board further comprises an insulating spacer layer, the insulating spacer layer is disposed between the packaging lead and the first main lead and between the packaging lead and the second main lead, and the insulating spacer layer is used to insulate the packaging lead from the first main lead and the second main lead. In the flexible circuit board, the insulating spacer layer enables the main lead and the packaging lead to not generate a short circuit caused by a tiny displacement in lead wiring or thermal breakdown, so the flexible circuit board has the advantages of good performance, high circuit reliability and the long service life.
Description
technical field [0001] The invention relates to a circuit board, in particular to a flexible circuit board and an LED flexible light strip with the flexible circuit board. Background technique [0002] As a fourth-generation lighting source, LED has significant advantages in energy saving and longevity. With the development of society, the problem of lighting energy consumption in daily life has become increasingly prominent. Therefore, LED lamps with significant energy-saving advantages are more and more popular. [0003] LED flexible light strips use flexible circuit boards. Because the FPC material is soft, it can be bent, folded, and wound arbitrarily, and can be moved and stretched in three-dimensional space without breaking. It is suitable for use in irregular places and places with small spaces, and because it can be bent and wound arbitrarily, it is suitable for arbitrarily combining various patterns in advertising decoration. Therefore, LED flexible circuit boards...
